Eh…..my Martin has a thinline inside the guitar. The only feedback I get is low frequency hums instead of screaching…sort of wwooooooo. hehe.I just run it exactly like my electrics……if it were more complex to use than an electric…I just wouldnt ever amp them….id only mic them. It really depends on your pickups. The stick on pickup..ive never trusted/liked those….im too rough on internal electronics, I dont need anything on the outside, (I even broke my cable the other day….the tip flew off of it). There isnt any of my guitars that havent had some wiring problems….some of them I got tired of wiring again and again so I ended up wiring them with guitar strings…..it sounds ssssssoooooooo much better that way, (I recommend the G). So my answer to the question is…yes, do it….if it screeches……turn a knob untill it doesnt.
